P80 series is rated for 1900 mA spinup current on the 12V rail, so by multiplying that by eight gives about 15A. The Nexus is also rated at 15A cont., so it might be too tight, especially as I didn't count other drives. IIRC KT7A uses 5V for CPU power (no 12V P4 connector?), so it doesn't put more strain on 12V rail.

After You get the drives spinning using a 300W PSU should not be a problem. If You want to play it safe, the new Nexus NX-4090 seems to have dual 12V rails.

Damm, I must have been drunk the last years, I didn't realize you where from this part of the woods too! Seing the location under your name was a small surprise, haven't seen that at storageforum.
Nice to see some friendly faces here

I just checked verkkokauppa, the local store I got my last nexus from, and they seemed to have the new Nexus you mentioned in stock. Guess I'll be ordering one on Monday. Thanks for the help! Gotta read through the latest posts here about it first.

Looking at the posts in this thread, there are only four large Molex connectors? Also there is no mention of the dual 12V rail, though it's somewhat mentioned on the Nexus site.

I think You need special cabling to supply power to all of those drives.

2) which controllers if any allow for staggered spinup for ATA and SATA drives?

At least 3Ware's current controllers (both PATA & SATA) support staggered spin-up. I've checked latest HPT's & Promise's controller manuals (briefly), and they had no mention of staggered spin-up. I can understand the lack in Promise products, as they currently offer only controllers which support up to four drives. HPT on the other hand has an eight-port solution, which could be too much for a regular PSU (when using the max. capacity of the controller, obvously! ) LSI doesn't mention staggered spin-up in the product brief of their newest SATA RAID controller, neither does SiI. Maybe 3Ware is the only one currently supporting this feature?

EDIT: See this post for more info and the original, unedited post.

OK, seems that I (again?) typed something before checking it out throughly. I've edited this post, and the unedited version is below.

Sorry.

Cheers,

None I know of. ATA command set doesn't support delayed spinup (in SCSI this is set by jumpering the drive correctly), which is needed for staggered spinup. Perhaps if there is a controller which also supplies power to the drives. Then it might work. Don't know what the status is for SATA.

I do remember one thread on StorageReview.com's forums where someone said that some IBM/Hitachi drive might support delayed spinup. IIRC even then the drive needed some special firmware (supplied to OEMs only) and/or a special controller (with special firmware), which would send the "do not spin up right now" command to the drive when the computer was booted. Sorry, my memory is vague on this IBM/Hitachi matter. Suggest You search for SR.com's forums.

That would be the main components worth mentioning, but the PSU is also running 6 fans on top of everything else. 2x120mm, 3x80mm and a Zalman CNPS7000A-AlCu. Is it silent you ask? Far from it, but it's pretty damn quiet for being such a file server. Everything is stacked into a Lian Li PC7077A that has been sound-proofed.

*Is most envious of the data space on that server...*

In any case, do all the hdds spin up at the same time, or are they staggered?

I think You boot from the onboard controller, yes? Do You run with dummy BIOSs?

I'm not quite sure if I understand you correctly, but...
I boot from the controller on the motherboard, but it is also possible to boot from a TX2 controller if I wished to do so, they have an "active" BIOS.

I've decided to go for an overclokable platform, so in future if i need to push the CPU for more power i will be able to do it.

After lots of google-ing and review reading i've narrowed down the list to these components and now i have to pick a Power supply for them but i'm a noob to both overclocking and power supplies and to make it all better i don't a have a lot of cash remaining for spending on a PSU, say max 55-60USD

In this pc i'd also have to have a lot of quietness and temps as low as the can go, hence the rather expensive heatsinks u'll see

here are the components i'd like to have powered by my PSU
Abit NF7-2S/Abit AN7 still thinking about it
Mobile Barton 2400+ vcore 1,35V version. that i will try to push to 2,4Ghz, 'm new at this and not feeling that lucky HSF - SP97 + ENERMAX 90mm UC-9FAB-B
2*256 ram sticks...still looking for the right model, pls consider average consuming sticks, probably i won't afford to buy high end stuff.
Tright NB-1+Delta on northbridge
Radeon 9600 pro 128bit 256 ram - video card WITH artic vga silencer revision3 instead of whatever stock cooling it comes with.
I alreay own a WD800JB 2 years now, so this will be the hard disk for start
Teac WD540
Asus 50x cdrom drive
No name Tv tuner
No name fdd
2 x Enermax UC-9FAB-B fans or 2x Panaflo L1A as intake exhaust fans for case
